If we know the equation of a circle we can graph the circle by identifying its center and radius. Expanding the standard form we get the general form of x 2 y 2 - 2 h x - 2 k y h 2 k 2 - r 2 0. Substitute in the values for x 1 y 1 x 1 y 1 and x 2 y 2 x 2 y 2.

The equation of a circle is.

X - h 2 y - k 2 r 2. Substitute the slope for m in the slope intercept form of the equation. You can input integers 10 decimals 102 fractions 103 and Square Roots - use letter r as a square root symbol. Connecting the points A and B with the point P makes an angle 90 between them.
